[C38] ugly tow

Actually the wave caused by the displacement of water by the hull builds
around the entire boat. I suspect Larry was being pulled up the front of
the wave a bit due to the force/speed of the tow. I also am guessing he
was seeing a lot of froth around the boat as it was kind of planing by
breaking surface tension of the wave (that is how we go faster than hull
speed at times). The problem is when the tow breaks and you are no
longer planing... or being supported up the wave. The stern part of the
wave poops you and the forward part of the wave causes the broach!
